The graphic (a snapshot from the animation) depicts the surface temperature increase (relative to the 1870-1899 period) from the average of a set of CCSM3 experiments of the IPCC AR4 SRES A1B (midrange) climate change scenario. The lower panel shows the global average temperature change from the same base period, illustrating the impact of five major volcanic eruptions, as well as the different IPCC AR4 SRES scenarios, Commitment (no changes relative to 2000 in greenhouse gasses), B1 (CO2 level stabilizes at 550 ppm), A1B (CO2 stabilizes at 720 ppm) and A2 (CO2 increases to 840 ppm at 2100).

These animations show the same features mentioned above. For the Krakatau and Santa Maria eruptions, the animations "slow down" to show the global cooling caused by these volcanoes. The 800x600 animations are suitable for PowerPoint or Keynote presentations. The 1920x1440 version is high-definition and isn't suitable for standard laptops. These animations are freely available.
